The NG tube insertion checklist serves an important purpose: by providing step-by-step guidance on how to safely insert the tube, it helps reduce the risk of errors or omissions that could lead to serious patient harm. The checklist includes key steps such as ensuring that proper positioning is maintained and radiographic confirmation of placement. Additionally, it should include instructions for adjusting the tube length and confirming that gastric contents are present before completion of insertion. Having this type of detailed protocol reduces the potential for accidental injury during nasogastric intubation.
